Application filed February 24, 1909. Serial 'No. 479,837.

To all whom it may concern:

Be it known that I, CHARLES I BAKER, a

States, residing at Lan Umbrella-Runners, of which the followingis a specification, reference being had therein to the accompanying drawing.

My invention relates to the construction of umbrella and parasol frames, and more particularly to that part of the frame known as the runner notch-pin or spider and the objects of the inventio .being to construct a device of this class for hinging the ends of the ribs and stretchers to the spider and runner, in such a way that they may be cheaply produced, quickly assembled or repaired, and in this connection it may be here stated that in the usual deends of the ribs or stretchers are retained, within a groove formed in the runner, by means of a wire upon which they are strung, and that when it is desired to replace a broken rib, they must all be detachedfrom the runner; while by the use of my novel construction each rib or stretcher is hingeably joined to the runner in an' independent manner from-the others, and each may be removed without disturbing any of the- Another object of my invention is that by the form of my ball and socket joint, the ribs may swing in both directions, and in this manner when the umbrella becomes accidentally blown insideout theribs will freely swing in the sockets on the runner without breaking said sockets, as is now the case with all of the present ball and socket hinged joints now in use for this purpose.

With these and other objects in view my invention consists in certain construction be fully described and claimed and which is illustrated in the accompanying drawings which form a part of this application, and in which like figures of reference refer. to parts in all of the views, but it is fully un erstood that while I have herea with described and claimed my invention as here illustrated, I do not confine myself to the exact design as shown, as slight changes the s irit of the invention.

bination of parts without departing from Re erring to the drawings forming a part of this application. Figurel, is an elevation of a partial view of an umbrella stick, showing the runner and the spider with a plan view of the runner. Fig. 6, is a bottom plan view of the same.-

In the drawings the umbrella stick is indicated by l, the fixed or end spider by 2, and it may here be stated that the construction of said fixed spider 2, is the same as that of the runner, which is hereafter described in detail, and which. comprises a tubular body portion 3, adapted to slide upon the stick 1, and be retained in the desired posi-' tion thereon by the usual 7 for this purpose. Upon the upper end of said tubular body 3, 1s secured in a suitable manner the socket head which comprises the ring 4, which is provided with radial "sockets 5, formed by the curved arms 6, between the edges of which are formed the slots 7, in which swing the ribs, or stretchers 8.

The ribs or strethers 8, are preferably in the form of a channel body, having their ends cupped and formed around a ball 9, thus forming an outer ball or spherical end 10. 7 This ball end 10, is retained within the two adjacent sockets 5, with the body 8, of the rib or stretcher-having a vertical swing in the slot 7 and it may'her e' be noted that unlike other devices of this class the slots 7,

, extend near enough to the center of the the ribs to swing freely stretcher toallow (in case the umbrella-is turned inside out), to keep the socket or ribs from breaking. To further guide and retain the ball ends 10,

from any side motion in the socket5, I have provided in the ring 4, midway between the slots 7 the raised bosses 11, which are here means employed .singlerib and stretcher attached thereto.

shown'as embossed from the bottom of said 5 rin In this manner it will be seen that the bal .ends of the ribs'or, -st-retchers and the runner or spider forni' a perfect ball and socket joint and that when it is desired to replace a rib the adjacent sockets may be opened by (curling back the lips and the rib the combination of the end of the ribs formed about. 1i ball, of a runner provided with curved radial arms, slots formed between said. arms, sockets formed within said arms, and the lower surfaces ofsaid arms provided with an enibossed portion to extend yvithin said socket forthe purpose set forth.

2. In a ball and soeket umbrella runner, in combination with ribs formed with spherical ends ot' a head secured u 011 said runner and formed with radial sockets spaced from each other and provided with a raised portion within said socket to limit the action of said spherical ended ribs.

In testimony whereof I aitix my signature I in presence of two Witnesses.
